Alton Nolen is accused of beheading Colleen Hufford in September 2014 at a food processing plant in Moore. Friday, the judge heard testimony from three people, including a man who witnessed the attack.

The man said he was speaking with Hufford when Nolen burst into the office carrying a large knife, and that he wouldn't stop attacking Hufford, even after other employees tried to intervene.

In October, a judge found Nolen mentally competent to stand trial, though a date has not been set. Prosecutors have indicated they will seek the death penalty.

Smollett reported being beaten up by two men who shouted racist and anti-gay slurs and threw bleach on him. But his story fell apart when actors Smollett knew from the "Empire" set and the gym told police that Smollett paid them $3,500 to stage the attack.
